Title: Improvements in and relating to copying lathes or like machines
IPC: B23Q11/00
Filed: 1966-07-04
Abstract: 1,108,418. Machine tool details. H. ERNAULT-SOMUA. 4 July, 1966 [26 July, 1965], No. 29978/66. Headings B3B and B3T. In an hydraulic copying lathe having a tool cross slide 6, Fig. 1, movable on a saddle 1, which in turn is movable on a bed 2, the distance L between the face of the follower 11 which engages the template 12, and the point of the tool 13, remains constant during expansion of the slide due to heating of the oil which operates the hydraulic piston 19 for moving the slide. Piston 19 is controlled by a valve 21. connected to a plate 24, secured to a lever 28 which carries the follower 11. The lever is pivoted to a spindle 32 carried by bearings 34, 35, Fig. 5, in the cranks of a crank-shaft 38 rigidly connected to a shaft 39 mounted in cross slide 6. A hub 43 secured to shaft 39 carries a crank 45 which can be slidable therein so as to adjust its effective length, and is connected to a compensating rod 47 pivotally connected to slide 6 at 49, Fig. 6. Rod 47 is made of material whose coefficient of expansion differs from that of slide 6. In operation, when the oil is cold, the slide is in the position of Fig. 6. After a period of operation the oil of piston 19 heats up, so that the length of slide 6 increases by an amount d, Fig. 7. The axis of shaft 39 has moved a distance d, whereas the axis 46 of the end of crank 45 has not moved, and the cranks 45, 36, 36 have moved through an angle b. The expansion is thus taken up without altering the distance L.

IPC: H02M3/156
Filed: 1967-06-29
Abstract: 1,177,553. Automatic voltage control. TECHNIPOWER Inc. June 29, 1967, No. 29996/67. Heading G3R. A D.C. voltage regulator comprises input terminals 6, 8; output terminals 10, 12; an inductor 14 having sections 16 and 18 serially connected with a rectifier 22 between terminals 6 and 10; a storage capacitor 24 connected across the output terminals 10, 12; a switching circuit 26 for controlling current flow in inductor section 16; and a flip-flop circuit 30 for controlling the mark/space ratio of the switching action of circuit 26 in dependence upon output voltage variations as detected by a sensing circuit 36 which is associated with a voltage divider 40, 42 connected across the capacitor 24. The voltages induced in inductor sections 16 and 18 by the switching of circuit 26 are added to the D.C. input voltage at terminals 6, 8, the D.C. output voltage of the regulator being thus higher than the input voltage and being maintained constant by the action of control circuits 30, 36; the components of the switching circuit 26 are not, however, subjected to this higher voltage, as the circuit 26 is associated only with the inductor section 16, and thus these components may be of a rating less than normally required. Suitable transistor arrangements for the circuits 26, 30, and 36 are described with reference to Fig. 2 (not shown). In another embodiment the inductor sections 16, 18 are not conductively connected and the section 18 has either a step-up or a step-down relationship with section 16 Fig.3 (not shown). The inductor 14 may have other sections, similar to section 18, providing further outputs, Fig.4 (not shown). The regulator may also include a conventional current sensing circuit which causes the switching circuit 26 to turn off under overload conditions.

Title: Improvements relating to injectors for locomotive boilers
IPC: F04F5/46
Filed: 1924-12-17
Abstract: 234,727. Friedmann, A., [Firm of]. Dec. 17, 1924. Giffard injectors; regulating or controlling action.-An exhaust steam boiler feed injector device for locomotive boilers is provided with a valve with two seating surfaces which is lifted to allow the passage of an auxiliary supply of live steam of reduced pressure to the injector whenever the engine is stopped or there is not sufficient pressure in the valve chest to keep seated a non-return valve. The valve 6 which is thus lifted allows live steam that passes into the chamber 14 from the inlet pipe 10 through the passage 13 to pass under the valve seating 7 and down through the pipe 4 to a. nozzle surrounding the inner live steam nozzle 3. The valve 6 has an upper and larger seating 8 which, when the valve is lifted, shuts off the chamber 9<a> from the chamber 14, and the chamber 9<a> is cut off from the passage by a non-return valve 12 when the engine is running. The seatings 8, 12 are roughened to allow leakage of steam even when the valves 6, 12 are closed. The pipe 11 is connected with the valve chest, and when the engine is running under steam the valve 6 is seated at 7 so long as the pressure difference in the chambers 9, 14 does not exceed a certain value; the passage 4 is then closed and the injector is operated by live steam flowing through the passage 2 from the boiler and exhaust steam flowing through the pipe 1. When the throttle valve of the engine is closed and the exhaust steam supply ceases, the valve 6 is lifted to supply steam at reduced pressure through the pipe 4 to the injector.

Filed: 1973-06-26
Abstract: 1374958 Valves SOC ANON DES ETABS JOUVENEL & CORDIER 26 June 1973 [6 July 1972] 30418/73 Heading F2V A multi-purpose valve device comprises three ports 12, 14 and 20, interconnection between which being controlled by a valve member 22 responsive to fluid pressure and an adjustable valve plunger 26 controlling an additional passageway 27 interconnecting ports 12 and 14. Port 20 may be closed off by a screw-plug (not shown). Valve member 22 includes a resilient annular lip 25 having a number of small orifices 24 which prevent the lip being damaged in the event of a sudden flow reversal. If a plug is inserted in port 20 the valve acts as a conventional check valve permitting flow between ports 12 and 14 provided plunger 26 is in its closed position. Opening of the plunger permits a restricted flow in the reverse direction. If the plug is removed from port 20 and plunger 26 is closed the valve acts as a high-speed discharge valve allowing free flow from port 12 to port 14 but when pressure falls at port 12 the valve member moves to open a connection between port 14 and port 20. With this arrangement the valve also acts as a flow selector between either port 12 or port 20 and port 14, depending upon whether the pressure is higher in port 12 or port 20.  In a second embodiment, Fig. 8 (not shown), performing the same functions, the valve plunger (26) is disposed in alignment with port (20) and has an axial passage therein, equivalent to passageway 16 of Fig. 1, controlled by a similar valve member (22). In a third embodiment, Fig. 9 (not shown), also performing the same functions and resembling that of Fig. 8, the plunger (26) is formed on an extension of the connector (18) in which the port (20) is located, the connector being screwthreaded for adjustment of the plunger.
